Abstract

Novel perhalofluoro ethers and methods for preparing the same having generic formula, ##STR1## wherein a=0 or an integer greater than O; PA1 b=0 or an integer greater than O; PA1 n=zero or an integer greater than zero; PA1 R.sub.f and R'.sub.f are each independently selected from the group consisting of F, perfluoroalkyl and fluorochloroalkyl; PA1 X=F, Cl or Br; PA1 X'=Cl or Br; PA1 Y is an acid group or a group easily convertible to an acid group; PA1 Z=F, Cl, Br, OH, NRR' or OA; PA1 R and R' are independently selected from the group consisting of hydrogen, an alkyl having one or more than one carbon atom and aryl; PA1 A=alkali metal, quaternary nitrogen, or R.
